James Hetfield admits he isn't always in the right frame of mind for a gig and says he relies on the audience to help him through the show.

The Metallica frontman says he makes eye contact with a member of the crowd whenever he needs a boost – and adds that the trick never fails. Watch the full interview below.

He tells Hitradio 03: "I mean, we're all human, and sometimes we feel very communicative and sometimes we don't. But most of the time, if I'm not feeling good and then we get up on stage, I just look at somebody in the eye and just say, 'Hey, I need your help tonight.'

"I mean, I'm not asking them directly, but through the eyes I'm asking them, 'I need your help.' And they give it to me, somehow."

The band last month made a new track, Lords Of Summer, available for digital download.
